(Information as of December 2025).

What is Spark (SPK)?

Spark (SPK) is the native token of Spark, an onchain capital allocator that borrows from Sky’s multi-billion-dollar stablecoin reserves and deploys them across DeFi, CeFi, and real-world asset (RWA) strategies. The goal is to unlock capital efficiency at scale while keeping a conservative risk profile and transparent, data-driven risk management. 

Instead of leaving stablecoins idle in fragmented pools, Spark aggregates and routes liquidity into lending markets, savings vaults, and RWA integrations—turning unused capital into productive yield. For users, this yield is packaged into simple products like sUSDS and sUSDC, yield-bearing stablecoins that remain fully composable across DeFi. 

SPK powers participation in this ecosystem as the governance and staking token, aligning long-term incentives for users, liquidity providers, and builders. SPK is issued as an ERC-20 token on Ethereum mainnet, with a fixed maximum supply of 10 billion SPK. 

The Purpose of Spark (SPK)

Spark was created to solve DeFi’s core capital problems: fragmented liquidity, unstable yields, and idle stablecoin capital. 

Its mission is to:

• Act as a two-sided capital allocator, sourcing liquidity from Sky’s reserves and deploying it across DeFi, CeFi, and RWAs

• Provide deep, programmatic liquidity so protocols can offer more predictable borrowing and lending markets

• Package diversified yield into programmable, fee-free stablecoin products that users can hold, move, and build with onchain
  

Rather than competing with protocols, Spark is designed to power them as the underlying liquidity and yield infrastructure for onchain finance. 

Why Choose Spark (SPK)?

Access to deep, scalable liquidity

Spark taps into Sky’s $6.5B+ stablecoin reserves and has deployed around $3.8B across DeFi, CeFi, and RWAs, contributing to roughly $7.9B in total value locked (TVL) across SparkLend and the Spark Liquidity Layer (SLL). These figures move with markets, but they show Spark’s scale as one of DeFi’s largest capital allocators. 

User-friendly yield products

Spark’s yield reaches users through Spark Savings, where deposits in USDC, USDT, USDS, or ETH are converted into yield-bearing sUSDS or sUSDC. These tokens stay fully composable, so users can earn while still using them as collateral, liquidity, or payment assets on networks like Ethereum, Base, Optimism, Arbitrum, Unichain, and Gnosis. 

SparkLend: transparent borrowing conditions

SparkLend is one of the largest lending markets in DeFi, with deep liquidity and governance-defined interest rates instead of purely utilization-driven pricing. Liquidity sourced via the SLL helps keep borrowing conditions transparent and reduces rate volatility for borrowers. 

Spark Liquidity Layer (SLL)

The Spark Liquidity Layer is Spark’s backend capital engine. It automates deployment of USDS, sUSDS, and USDC into protocols like Aave, Morpho, and RWA products such as BlackRock’s BUIDL, across multiple chains. One flagship deployment on Base is the Spark USDC Morpho Vault, which has supplied tens of millions of USDC and has been highlighted as a key liquidity provider to Coinbase’s USDC lending integration on Base—helping smooth rates and deepen market liquidity. 

How Does Spark (SPK) Work?

At its core, Spark operates as an active allocator of stablecoin liquidity. It sources capital from Sky’s reserves and, through the Spark Liquidity Layer, deploys and rebalances that capital across multiple networks and strategies according to governance-defined risk parameters and yield targets. 

Spark Savings vaults convert deposited stablecoins into sUSDS or sUSDC, which then participate in these underlying strategies while remaining fully onchain and programmable. SparkLend taps into the same liquidity so borrowers can access large-scale, competitively priced credit with clearer, governance-set rates.
